Trees for Houston offers a charitable take on the Christmas tradition.

You may have already trimmed your own tree this year, but have you considered gifting one?

Trees for Houston, the non-profit that does exactly what you think it does, hopes you might: With a donation of $30 or more, you can plant a tree in the city in honor of a loved one.

Dubbed “Holiday Tributes,” the trees are sized according to donation–$310 plants and maintains a 6 to 8-foot tall tree, and $450 sustains an 8 to 12-footer–and one can absorb as much as 48 pounds of carbon dioxide per year.

Trees for Houston also reports urban forests reduce temperatures in a city as much as 10 degrees F–come July, we’ll take it.

While it’s pricier to maintain the aforementioned 15- or 30-gallon trees, any donation above $30 will help Trees for Houston continue to “plant, protect and promote trees in the greater Houston region,” and the organization will also send your recipient an acknowledgement card and a handmade, plantable seed paper ornament.

Your gift will water one tree for a year for $75, or two years for $150. To date, Trees for Houston has planted more than half a million trees around the city over the last 34 years.

If you’re feeling even more charitable, the organization is hosting a “Holiday Happy Hour” toy drive on Thursday, December 14.

RedBuds, the young professional arm of Trees for Houston, will hold a mixer at The Owl Bar from 6 to 8 p.m. Anyone who brings a toy donation–think stuffed animals, books or games–will receive a free drink and pizza. The gifts go to Blue Santa, a Houston non-profit that provides toys to underprivileged children.

One charity, two chances to get on Santa’s nice list this year–there’s still time!
